termiual joint of antenna-, but I prefer at present to leave it in tlii 

 genus. 



DIPLOTAXIS BREVISETOSA, new species. 



Ovate, convex, rufoferrnginous or rufopiceous, shining, sparsely 

 pubescent with very short seniierect seta*. Head convex, sparsely but 

 coarsely and deeply punctate; clypeal suture obliterated except a short 

 groove at the eye. Clypeus more densely punctate, rounded, slightly 

 truncate at aj^ex, Avith niaigiu distinctly retlexed, antenna' lO-jointed. 

 ferruginous. Palpi ferruginous. Thorax nearly twice broader than 

 long, broadest at middle (in 1). iniherulns and iwpino the thorax is 

 broadest behind the middle), slightly narrowed to base, arcuately nar- 

 rowed to apex; all the angles rectangular; apex somewhat narrower 

 than the base, truncate, with a membranous margin ; base arcuate at 

 middle ; disk moderately densely and deeply punctate. Scutellum semi- 

 oval, with a few punctures at base, smooth at apex. Elytra at base 

 hardly broader than thorax, slightly wider posteriorly; costai not very 

 distinct, each with a series of punctures; intervals with slightly larger 

 punctures of the same size as on thorax, subseriately arranged at 

 the sides. Pygidium deejdy jjunctate. Thorax beneath densely and 

 coarsely punctate. Abdomen nearly smooth at middle, coarsely punc- 

 tate at the sides. Legs sparsely punctate and hairy. Anterior tibiae 

 tridentate, the two apical teeth strong, the upper one small. Claws 

 cleft at apex: the inferior part nearly as long as the superior, oblique 

 at ai)ex. Length, 6.5 to 7.5 mm. 



Six examples from Brighton, Nueces County, Texas. 



Ti/pe.—^o. 212, U.S.N.M. 



Of the hairy species of Diplotaxis, the sordida of Say, is large 

 (11 mm.) and has the anterior thoracic angles acuminate; />. 2>i(b€rulus, 

 LeConte, is elongate and has the anterior thoracic angles obtuse, and 

 D. popino, Casey, has truncate and angulate clypeus. All of these 

 species have longer hairs. D. crilmlosa, LeConte, is described as having 

 short hairs, but the head is densely punctate and the clypeal suture 

 impressed. 



COPRIS MCECHUS, LeConte. 



A specimen of this species, previously recorded only from Texas, was 

 collected at Los Angeles, California, by Dr. AY. J. Karlsioe (November, 

 1891). 



LACHNOSTERNA KARLSIOEI, new species. 



(Group ///scrt of Horn.) 



Robust, oblong, parallel, rufopiceous, very shining. Clyi)eus very 

 wide, distinctly emarginate, sparselj^ punctate; margin moderatelj' 

 retlexed; front more densely punctate. Thorax broadest at base, arcu- 

 ately narrowed to apex; margin very indistinctly crenulate; surfiice 

 moderatel}' coarsely, not very densely, punctate; punctures umbilicate;
